ROTARY ENGINE.

Application filed November 20, 1914.

7 '0 all whom it may concern:

Be it known that I, FRANK H. PARDON, a citizen of the United States,residing at Owensboro, in the county of Daviess and State of Kentucky,have invented a new and useful Rotary Engine, of which the following isa specificationj The present invention relatesto improvements in rotaryengines, one object of the present invention, being the provision of aconstruction of engine, in which the active portion of the rotor iseccentric to the carrying portion thereof and by means of which the sameis adapted to coijperate with an oscillatory abutment that engages atall times the periphery of the eccentric portion of the rotor.

A further object of the present invention, is the provision of means forcausing consonant action between the parts so that the abutment isproperly positioned at all times for directing the exhaust pressurefluid away from the engine, while the pressure fluid is admitted forexpansive force at the opposite side thereof.

A still further object of the present invention, is the provision of anovel form of balancing means, by means of which the active portion ofthe rotor may beproperly balanced for high or low speed.

A still further object of. the invention, is

the provision of a rotary engine of exceedingly simple construction, andbeing composed of few parts the same is made more durable, efficient andpractical in operation.

In the drawings Figure 1 is a longitudinal sectional view through theengine taken upon line 1-1of Fig. 3.

Fig. 2 is a top plan view of the complete engine. a

Fig. 3 is asection taken on line 33 of Fig. 1.

Fig. 4 is a perspective view of the eccentric strap and the connectionwith one of the abutments. i

Fig. 5 is a perspective view of one of the adjustable weights.-

Fig. 6 is a view similar to modified form of abutment.

Figs. 7 and 8 are detail views of the abutment per se.

Referring to the drawings, the numeral 1 Fig. 3, of a designates thechamber portion of the statorwhich has attached thereto, the respectiveheads 2 and 3, having their respective shaft Specification of LettersIPatent.

carrying members 4 and 5. The shaft 6 is journaled in the heads asillustrated, and as here shown is provided with the two active members 8and 9 spaced by the cylindrical portion 10 therebetween. The activemembers 8 and 9 are eccentric to the chamber of the stator and also tothe portion 10, and are oppositely disposed to produce the desiredbalance effect.

Each active member 8 and 9 is recessed as at 11 and provided with theradial bar 12 which receives the slot 13 of the adjustable weight 14,thebar 15 and set screw 16 being provided to permit of the properassembling of the weight 14 and the adjustment thereof relatively to thebar 12. It has been pointed out hereinbefore that the parts 8 and 9 ofthe rotor are oppositely disposed, to produce the desired balanceeffect. It is not possible to secure a perfect balance in this way,although an approximate balance may be obtained. A perfect balance,however, may be brought, about by a proper shifting of the adjustableweights 14,radially of the rotor. 1 l

The pipe 17 is the fluid conducting pipe, such fluid being preferablysteam, the same emptying into the bypass 18, which is c0mmon to bothnozzles 01' jets 19 sothat the steam may be conducted to the respectiveactive members 8 and 9 of the rotor at the angle as illustrated in Fig.3.

There is formed in the stator 1 as illustrated in Fig. 3, one to eachactive member of the rotor, a chamber 20, which is provided with theinlet 21 and with the exhaust pipe 22 leading therefrom. The blade 35 ofthe pivoted abutment 34 as will presently appear is mounted for slidingmovement through the port21 to engage the periphery of its respectiveactive portions 8 and 9 of the rotor and thus prevent steam afterentering through the nozzle or jet 19 from passing to the left a shownin Fig. 3, so that the expansive force of the steamwill be exerted uponthe eccentrically disposed active member 8 or 9 to rotate the same inthe direc-l tion of the arrow as indicated in Fig. 3, such pressurefluid being finally exhausted through the port 21, it being conductedthereto by the blade or abutment 35 when in the position as shown inFig. 3. In Fig. 3 it will be understood that as the rotor turns, theexhaust steam is pocketed between the periphery of the portions 8 or 9,upon the one hand, and the Wall of the stator 1,

byfr'neans of the tapered pin 24. Surround ing the eccentric is thestrap 25, there being interposed the antifrictional roller bearingflq toreduce the friction therebetween. Each strap 25; isprovided with the"p'itman 2'1 ,ivhich is operably connected by the pin 2 8 to one end ofthe rocking arm 29. The

opposite end of therocking arm is connected} to its respective rockshaft 30, which is journaled in th e stud 31 and is anti-fricuonauy'supported by the ball bearings 32, so that" the shaft 30 Will beoperatedwith the least possible friction. Eixedup'onthe sh'aft 30f nfithin the 'respective chambers 20 of the statoi is the arm '34,Whiclicarries the abutment or blade 35 heretofore specifled, Itvvillithiis b'fseen that" as the shaft fi iis rotatedj, the blade 35Will be at all times maintained in "contact with the periphery ofitsactive member Sor 9, and thusinsure a steam tightjoint at this pointso that the exhaust steam Will be properly direct-ed into the "port'2Iandtl'1 r0uglrthfe chamber 20 to the exhaust pipe 22" As there ar'etwo ciismterseo"; there are also two abutments 35 afidftwo' exhaustports 21 and 22. i i
